Set near/far clip distance for the visualization window camera

When viewing an outdoor gazebo world from some distance above, I get strong Z-fighting artifacts between two ground planes located on top of each other at a distance of about 0.5 meters. I suppose this could be fixed with a more suitable near and far clip distance for the visualization camera. Is there a way to set this distances in gazebo? Is it possible to access the camera parameters using a Gazebo-GUI-Plugin?

Hey guys, we have also the problem with z-Fighting. Is there any possibility to modify the near clipping plane??? A solution or even some advice would be great!! Best regards!!

It should be possible to do it from a GUI plugin. Just get the user camera:

rendering::UserCameraPtr camera = gazebo::gui::get_active_camera();

And set the new clip distances:

camera->SetClipDist(near, far);

For future users that stumble across this issue and would like to avoid writing their own plugin, the NASA IRG GitHub repo has a plugin that solves this problem
